2 Best Sights in Druid Hill Park, Baltimore

More than 2,000 animals live in the Maryland Zoo in Baltimore, the third-oldest zoo in the country. Elephants, lions, giraffes and hippos are among the park's roaming game. The zoo's centerpiece is a new African penguin habitat, a state-of-the-art facility surrounded by water housing the country's largest breeding colony of Afircan penguins. Other exhibits feature a giraffe-feeding station, the polar bear arctic pool, and a petting zoo with a re-created barnyard. Also, don't miss the Jones Falls Zephyr, a locomotive modeled on an 1863 locomotive that takes visitors on a 10-minute ride alongside the African Journey exhibit. Surrounding the zoo is grand, leafy Druid Hill Park, which was designed by Frederick Law Olmsted Jr.

This often-overlooked museum lets you travel back to an era when streetcars dominated city thoroughfares. A film traces the vehicle's evolution, there are beautifully restored streetcars to explore, and, best of all, you can take unlimited rides.
